上記カンパニの宣伝広告によれば、義歯用の人造頭蓋
骨の構造は以下のようになっている。According to the advertisement of the above-mentioned company, the structure of the artificial skull for denture is as follows.

てられた状態では緩むことはない。The lower jaw model is fixed on the lower jaw mount via a mounting screw. Similarly, the upper jaw model is also fixed to the connecting plate by mounting screws. The connecting plate is fixed to the lifting plate by a mounting screw or a tightening screw. This suspension plate is one component of the adjustable framework. Each denture is threaded and screwed into the corresponding jaw model. Such a screwed connection does not loosen in the assembled state.

Such disassembling operations are complicated and time consuming. The screw connection of the individual denture can then be loosened only in the disassembled state. The replacement denture can be removed only after loosening the screw connection. The new denture is then installed in the reverse order of the removal procedure. Such a procedure involves a considerable loss of time. It will be a considerable burden for the research students involved in the dentistry business.

Therefore, for example, the denture to be replaced can be pulled out by the usual extraction pliers according to the extraction procedure. Also, the new denture can be inserted by applying forced or strong acupressure. Therefore, the mounting is easy and the mounting time can be shortened, and the denture can be surely mounted at a predetermined position even in the processing work thereafter.

触面５を有する。As shown in FIG. 2a, a columnar shank 3 is attached to the denture, and this columnar shank 3 is inserted into a cutout portion 1a formed in the lower jaw model 1. At this time, the columnar shank 3 itself is maintained by the elasticity of the material of the lower jaw model 1. In this embodiment, a recess 7 having inclined surfaces, that is, tapered surfaces 7a and 7b is formed on the cylindrical shank 3. In this recess 7, while extending in the vertical direction,
A leaf spring 8 having an inclined surface, that is, a tapered surface 8a, 8b is engaged. As shown in FIG. 2b, these tapered surfaces 8a, 8b
Are inclined in the plan view. Denture 2
The side surfaces of the leaf springs 8 that engage with the recesses 7 in the cylindrical shank of are aligned over all the cylindrical shanks of the plurality of dentures 2.
Moreover, the length may be formed so as to engage with the recesses of these cylindrical shanks. The leaf spring 8 may be formed, for example, by being inserted into the insert member 14, or the insert member 14
It may be formed integrally with. The denture 2 has a flat or flat contact surface 5 formed on the side surface located on the lower jaw model 1.

そこで、弾性手段により確実に保持される。When the denture 2 is held only by the elasticity provided by the material of the jaw model 1, the denture is naturally removed from the lower jaw model 1 when the denture 2 is pulled out for replacement. However, in the embodiment with elastic means as described above,
The denture can be pulled out from the lower jaw model 1 after the engagement with the elastic means, for example, the leaf springs 8 and 10 is released. The new denture is inserted into a predetermined position in the cutout portion 1a of the jaw model 1 and pushed to a predetermined final position by forced or strong finger pressure,
Therefore, it is securely held by the elastic means.
